Can someone please help? As it says in the title, im trying "create" an alphabet in PHP, which my gf and I can only understand (it's a little thing that i thought to have with her), but im facing some problems.
I have this code here in HTML and PHP which its purpose is to replace an alphabet letter to some other character.
